"Malibooty" Workout LOVE THIS! It actually works. All you need to do is increase by 10 every 3 days . You will really feel your ass the next day! Running doesn't do anything for your butt, just makes you more aware of the fact that it's wobbly!
Stretch for 10 minutes. Skip for 5 minutes. Jog for 10 minutes. Run for 10 minutes. Walk back. Do 50 crunches. Being lazy might feel good at the time, but being active feels better in the long run. How badly do you want it?
